LOCKING BU'TTN Application filed February 18, 1929.

The main object of this invention is to provide a button which may be detachably secured to a garment or article of apparel.

Another object of this invention is to provide a detachable button for garments or the like which may be releasably locked in place in its entirety.

The above and other objects will become apparent in the description below, in which characters of reference refer to like-named parts in the drawing.

Referring briefly to the drawing, Figure 1 is a longitudinal, sectional, elevational view through the button.

Figure 2 is a bottom plan view of Figure 1.

Figure 3 is a top plan view of Figure 1.

Figure 4 is an enlarged, front elevational view of the stud and locking flange mutually engaged.

Figure 5 is an enlarged elevational view of the flange, showing the means of securing the sliding bolt in place on the flange.

Referring in detail to the drawing, the numeral 10 indicates the circular button which is adapted to be slipped through buttonholes.

This button 10 is provided with a bore 11 which is surmounted by an annular recess 12. The head 13 of a threaded stud 14 is inserted into the recess 12 of the button 10. .".Q This head 13 is unitary with the threaded stud 14 and the latter is provided with a slot 15 which extends longitudinally through the greater portion of the length of the stud 14.

The stud 14 passes through the bore 11 of the ifi but-ton head 10 and projects somewhat from the opposite side thereof. The threaded stud 14 is inserted into a threaded hole 16 formed axially in a locking flange 17. Said flange 17 is adapted to be rotated upon said stud 14 43 to adjust the distance between the flange 17 and the button head10 in which the material of the article of apparel is retained. A radial, dovetailed channel 18 is formed in the flange 17 and extends from its peripheral 43 edge to the hole 16. rFhe bottom surface of this channel 18 is corrugated, as indicated by the numeral 19, throughout its length. A

locking bolt 2O is received in the channel 18 and is provided with a corrugated lower surface 21 which engages and seats upon the Serial No. 340,703.

corrugated surface 19 in the channel 18. This locking bolt 20 is slitted at 22t0 provide resiliency for the lower half of the bolt 2() and above this slit 22 the locking bolt 20 projects upwardly so that it extends from the face of the flange 17 and may be manipulated by the fingers.

rlhe button consists of a head 10 which is mounted on the outside of the article of apparel by means of the stud 14 and flange 17. The stud 14 is inserted into the bore 11 of the button head 10 and the head 13 of the stud 14 is inserted into the recess 12. f This stud `14 is then-permitted toy pierce the fabric of the article of apparel and the flange 17 is then threaded upon the stud 14. To lock this flange 17 in place, the bolt 20 is shifted toward the center of the flange`17 until one of the ends 2O ofthe bolt 20 is received into the slot 15 formed in the stud 14. The button is then securely attached in place Von the garment and cannotbe removed unless the operation is reversed. One end of the locking bolt 2O is made resilient so that its corrugated surface 21 will frictionally engage the corrugated surface 19 of the flange 17, thus releasably locking the bolt Q0 in any desired position inthe flange.

It is to be noted that certain changes in form and construction may be made without .departing from the spirit and scope of the invention.

Ve claim: .j

1. A detachable button comprising a button head', a threaded and slotted stud projectingfrom said button head, a threaded flange engagingl said stud, said flange having a dovetailed radial channel therein, a locking bolt slidable in said channel, said bolt being adapted to be urged into said slot to secure said stud in said flange, and resilient means on said bolt for frictionally retaining said bolt in any desired position in said channel.

2. A detachable button comprising a button head, a threaded and slotted stud projecting from said button head, a threaded flange engaging said stud, said flange having a dovetailed radial channel therein, a locking bolt slidable in said channel, said bolt being adapted to be urged into said slot to secure said stud in said flange, said channel having corrugated surfaces extending throughout its length7 said bolt having one end slitted, one side of said bolt being corrugated, the corrugated side of said bolt seat-ing upon the Corrugated surface in said channel, said corrugated surfaces being adapted to `resiliently cause said bolt toreinain in any desiredpostion.

In testimony whereof We aX our signa-vA tures.
